T470 plugged in but not charging, new battery still doesn't detect-English Community
Second battery is not charging to its fullest capacity (T470s) : r/thinkpad
New T480, second battery not charging. Is it possible to somehow force the charging process? Battery has just 4.6 volts, and only 1 charge cycle. I dont believe it degraded so quickly
